vill. 262. But the question here properly is, whether Dr. Anders- 
son knew the dasyclados of Wimmer, for he had the acuminata 
of Smith then before him. In the Prodromus, dated 1868, 
Andersson still places the dasyclados under acuminata, as “ huic 
sine dubio affinis si non cum ea identica”. 
Salix stipularis, Sm. 
Provinces 123845-7--10---141516. Very uncertain. 
Ambiguity. Crowe, in E. F. Leefe Sal. no. 21, fide Andersson. 
“This plant I have never seen alive, and possess no specimen of 
it”; Eng. bot. viii. 226. By the records, many of doubtful 
reliability, its area extends from Devon to Islay (Balf. cat.) and 
Forfar (G. Don, Gard. flo.). Marked as common about the Forth 
counties (which are botanically familiar to Dr. Syme) in the Cata- 
logue of Edinburgh Plants. And in the Flora Scotica, on authority 
of D. Don, it is stated to be common in Scotland. 
Salia Pontederana, “ Willd.” E. B. 8. 
Province - 5. Shropshire. 
Ambiguity. “No. 86 of Leefe’s Sal. Brit., which is from Shrews- 
bury, collected by the Rev. W. A. Leighton, is said by Andersson 
to have much in common with 8. Pontederana.”... .“ The 
specimen in my set is rightly named S. ferruginea”; Eng. bot. viii. 
262. Andersson’s words are “Valde dubia forma. Multa cum 
Salice Pontederana habet communia; foliarum forma iis Salicis 
holosericeze W. similis. Nil certe de hac enuntiare audeo”; Bot. 
Gaz. iii. 59. In conformity (Prodromus, 1868) we find him place 
S. holosericea (of Koch’s Synopsis) as a synonym of his Smithiana 
var. velutina, and ferruginea (of Anderson and Smith) as a sub- 
variety of his own velutina. ‘“ Pontederana” is a name of various 
application by Andersson, to include presumed hybrids between 
purpurea, on one side, with caprea, cinerea, and aurita. 
Salix grandifolia, Ser. 
Provinces - 14 15 16. All of them very doubtful. 
Ambiguity. Dr. Andersson wrote this name at the corner of a 
sheet of five specimens, brought from the counties of Perth and 
West Inverness; but I cannot certainly say that he intended the 
name to apply to all of them. More doubtfully, the same name 
was suggested for a willow picked near Queensferry, Linlithgow- 
shire, in 1831; which Mr. Macnab, senior, then named for me (a 
student) aquatica. I now refer all six specimens to caprea, but to 
that form of it with pointed and nearly entire leaves, which was 
alluded to under sphacelata, on page 567. I have not seen the 
catkins; the leaves differ considerably from those of caprea, as 
usually seen in England. 
Salix propinqua, Borrer in E. B. 8. 2729.
